Croatia
S-300 missile
A cable written by the U.S. Ambassador to Croatia Ralph Frank in November 2003 reveals the American interest in obtaining the S-300 surface-to-air missile system from Croatia. The Croatian government acquired the system in 1995, before the Operation Storm, but it was incomplete and was never operative. According to other sources, including the court testimony of arms dealer Zvonko Zubak, the system was indeed shipped to the U.S. in 2004.
